To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed parts are acceptably
insulated from the supply circuit) before the appliance is returned to the customer.
The DC voltage is an actual reading measured with a high impedance type voltmeter. The measurement value may vary depending on
the measuring instruments used or on the product. Refer to the voltage during PLAY unless otherwise specified; The value shown in ( )
is the voltage measured at the moment of STOP.
